Sponge filters provide both mechanical and biological filtration. Simply install an airline into the unit and provide both aeration and filtration for your fish. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. In addition, the sponge traps larger waste particles mechanically cleaning the water without trapping baby fish.

This works as a breeding filter or secondary filter. This may also be used as a pre-filtration unit by fitting to an external or a top filter.

How Does It Work?

A sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge. As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge. The sponge is a mechanical filter and the surface of all the bubbles or pockets in the sponge provide a bed for the bacteria of a biological filter. The bacteria help to break down harmful waste (ammonia and nitrite). Sponge filters provide both mechanical and biological filtration.

Most sponge filters are reasonably efficient filters for small volume tanks. These filters are excellent for small-sized fish like dwarf cichlid, guppy, killifish etc., or for hatcheries, maternity tanks, and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter. Also, the air infusion chamber produces minute bubbles which increase the oxygen solubility.

Required Maintenance

The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks. It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.

After 3 to 6 months of use, the pores within the sponge will get clogged by the tiny debris, and as such, beneficial bacteria won’t have as much living space as before. As a consequence, the sponge will begin losing its efficiency. With this, it is recommended to replace the sponge once every 3 to 6 months, or whenever the sponge gets worn out.
